'LOUI BLRIOT, OF `NEUILLY-SUR-SEINE, FRANCE.

RADIATOR FOR FLYING-MACHINE MOTORS.

To all whom it mayconccrn.'

`Be it known that I, LOUIS BLRIOT, en-

n e i gineer, a citizen of the French Republic, re-` siding at 56 boulevard Maillot, Neuilly-sur- Seine, France, have invented certain new and useful Improvements in Radiators for Flying-.Machine Motors, of which the following is a specification.

This invention relates to improvements in the cooling of the circulating water or other fluid in motors of dirigible balloons, aeroplanes and similar apparatus, and consists in using for the said cooling either the usual surfaces of the apparatus inV question, or additional surfaces suitable for contributing to the support of theapparatus. It becomes possible therefore, to remove simultaneously all the disadvantages inherent in the usual cooling systems, both from the point of view of their installation and the resistance which they offer to the movement of the same apparatus. l

In order that the invention may be clearly understood reference may be had to the accompanying drawings in which two constructioiis of the invention are illustrated.

` Figures 1 and 2 are respectively plan and longitudinal section of apartof the first of the said constructions which is more particularly suitable for the use of ordinary cooling surfaces. Figs. 3 and 4c are respectively plan and cross-section, the latter on an enlarged scale, of one of the elements comprised in the second of the said constructions, Awhich is more particularly suitable for the utiliza tion of additional supporting surfaces for cooling. Fig. 5 shows in .perspective a radiator designed in accordance with thesarne construction. Fig. 6 finally shows diagrammatically in front elevation an aeroplane provided with radiators of the kind shown inFig. 5. i The construction shown in Figs. l and comprises a 'series of capsules, annular crowns or,.cups a of the shape shown in the drawing or of any other suitable shape, secured in any suitable manner, for instance by means of rivets b, with or Without" interposition of packing joints or rings, to a iexible sheet c which may advantageously be a thin aluminum sheet, the said cups being connected together by means of branches al and flexible unions d. Owing to that arrangement all the cups a and the whole ofv the sheet c constitute 'a thoroughly flexible Specicaton of Letters Patent.

system which can be utilized for lining-the whole or Ipart of the usual surfaces (body, wings, etc.) in place of paper or fabric.

The construction shown in Figs. 3 and 4 is similar to the first, `with thc exception that the `cups a are replaced therein by elongated parts a arranged in pairs, so as to form complete cooling elements with the sheet c which is of considerable thickness, i

so that it may be used for a supporting surface and with inlet branches (Z2, connection branches (Z3 and outlet branches di. The system is then utilized advantageously by arranging it as shown in Figs. 5 and 6, that is to say, by superposing a certain number ofeleineuts such as those mentioned and shown" in Figs. 3 and 4L mounted either iixedly or movably about a certain axis, and adding to them tanks which can be consti- 4tuted advantageously of two vertical boxes e2 and 6*, arranged with their' longer sides adjacent and arallel, one of thenibeing connected to the inlet branches d2 and the other to the outlet branches d4 of the various elements. In that way an excellent circulation can be obtained.

It niust be understood that the expression circulation water used in the beginning of this description, is intended to comprise not only cooling water ofexplosion engines, but also feed water of steam engines.

It is obvious that the invention is not iu way limited to the construction dcscribed, and that itcOmprises all possible variations.

'Having now particularly described and ascertained the nature-of my said invention andiii'- what manner the saine is to be performed, I declare that what I claim is surface, the latter forming a common wall for the members, and providing for inclosed l circulation spaces, connections between the members, means whereby water may be conducted from the motor' of the machine to Howv successively through the members, and means for returning the water to the motor.

2. In an aerial machine, the combination with one or more flexible sheets, of a cooling device for the circulation water ofthe motor, v

comprising a series of interconnected cups arranged `on each sheet, the latter fornnng a common wall for the cups, means for conducting water from the motor to flow through the cups and means for returning the water to the motor. 3. In an aerial machine, the combination with one or more iexihlc sheets, of a cooling (lcvice for the circulation water of [he motor comprising a series of interconnected annular cups, means for conducting water from the motor to How through the cups, and means for returning the Water to the motor. 4. In an aerial machine, the combination with a plurality of sheets, of a cooling device for the circulation Water of the motor comprising a series of interconnected cooling and circulation members arrangedon each sheet, the latter forming a common wall for the members, and a pair of tanks, one of which serves as a reservoir on und conncci'wl to 'the admission side of the cooling (lcvcr :uul (hc olhcr ol which serves ns reservoir ou` uml couucclml lo ilic escupe sifle of the cooling device.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
